[Elecraft] Case for noise generator

Sat Aug 22 08:28:13 EDT 2009

And if someone figures out how to make it or the  XG1 work on 10M I would be
very interested. Tried a 10M fundamental crystal and played a little with
the caps, but no luck so far.  I use 10M to measure coax loss to the tower
on all my buried coax lines.
I changed the crystal to 160M with a XG1, that works well with a whip
antenna for checking receive antennas.

Maybe Elecraft will come  out with an XG6 in a case?

Joe,

Not required IMHO.  Dave said they would be made with a sliding cover.
It should be easy enough to slide the cover back and access these 
controls - IMHO that is easier than providing screwdriver access holes.

Perhaps I am speaking only from my own experience, but I use the XG2 a 
lot, and the bandswitch stays on 40 meters and the slide switch stays at 
the 50 uV setting almost all the time.  Yes, I am typically adjusting 
the CAL S HI setting, and I do that on 40 meters with the preamp off.  
The other settings are used but very seldom.

I realize I am not the 'normal' user, and I have an HP8640 on the 
workbench too if I need additional levels and frequencies, but the XG2 
is just so handy, I can't resist using it.

Now if Elecraft would provide another mini-module - the same high level 
xtal oscillator circuit as shown in the K1 and K2 manual troubleshooting 
section, that would make a great addition to the set of test instruments 
- I use my HP8640 (which goes up to +20 dBm) for that, but most builders 
do not have that capability, and an inexpensive high level signal source 
would be a real asset.
